question 4(multiple choice worth 6 points)
(03.04 mc)
which of the following is most likely to form when hot magma rises up as tectonic plates move apart below the ocean?
mid - ocean ridge
fault
trenches
subduction zone

Explanation:

When tectonic plates move apart (divergent boundary) below the ocean, hot magma rises. Mid - ocean ridges form at such divergent boundaries. Faults are fractures due to stress (not specifically from divergent oceanic plate movement). Trenches and subduction zones are associated with convergent boundaries (where plates collide, one goes under another).

Answer:

Mid - ocean ridge
